For molecular modelers, clarity is key. When working on complex molecular structures in tools like SAMSON, ensuring that your labels remain legible while managing zoom levels is a common challenge. Have you ever found your workspace cluttered with unnecessary labels when zoomed out—or worse, missing important ones when zoomed in? The good news is that SAMSON provides an intuitive way to control label visibility to keep your view clear and information-focused.
Why Fine-Tune Label Visibility?
Labels in SAMSON serve as essential markers for nodes in your molecular designs, displaying critical details about atoms, bonds, residues, or molecules. However, an overabundance of labels—especially in intricate systems—can make your viewport overly busy. Conversely, lacking enough labels during detailed inspections can leave you scrambling for information. Adjusting label visibility ensures that your workspace adapts dynamically as you zoom in and out on your molecular systems.
How Visibility Adjustments Work
In SAMSON, labels are cleverly designed to change their visibility progressively. When zooming out, smaller nodes (e.g., atoms) start to lose their labels while larger nodes (e.g., molecules) retain theirs. This gradual shift ensures your focus stays on relevant elements according to the zoomed perspective. The opposite happens when zooming in—labels reappear for smaller nodes as they fill more of your screen space.
If you’d like customized control, you can modify a label’s visibility range. This is dictated by two parameters:
- Minimum Display Radius: The smallest zoom level at which a label appears.
- Maximum Display Radius: The largest zoom level at which a label disappears.
How to Adjust Label Visibility
Here’s how you can take control of label visibility in SAMSON:
- Select the label you want to adjust.
- Open the Inspector in SAMSON’s interface.
- Locate the maximum and minimum display radii options.
- Modify these values to specify when the label will appear or disappear as you zoom in or out.
With just a few tweaks, you can reduce visual clutter and ensure the right information pops up exactly when you need it.

Take Full Control with Customization
Getting labels to appear at precisely the right levels of zoom allows you to maintain clarity without sacrificing important details during molecular modeling. Whether you’re working on simple molecules or complex assemblies, SAMSON’s tools make it easy to fine-tune your workflow. Experiment with these features and see how your modeling experience improves.
